When a shop begins the manufacture of rotating shafts, they frequently turn to their conventional CMM for part validation. However, this is often a case of using the tool that is at hand, rather than one designed for the job. 

As related to form metrology, a roundness measurement defines how closely the shape of a part approaches that of a perfect circle. 

Quality Vision International (QVI®) announced the newest precision optical instruments for measuring shafts and other cylindrical parts – QVI TurnCheck™.

The ProTable-TUBE is made for fast, simple, digital measurements of tubes & shafts up to 3 in. in diameter. 

In today’s manufacturing environment high-precision noncontact optical shaft metrology is a solid investment, whether it’s an entry level SPC measuring station operated by the workers or a fully automatic system for 100% part inspection.
